Development of an autonomous in-situ instrument for long-term monitoring of Cu(II) in the marine environment

Creator:: Holm, Christopher E.
Abstract:: An autonomous, in-situ instrument was developed to detect dissolved copper in seawater, suitable for deployment on time scales from weeks to months. A commercially available in-situ nitrate analyzer (YSI 9600) was adapted to measure copper (II) in seawater by chemiluminescence. Modifications included construction of a photomultiplier (PMT) based detector and...

Glacial to holocene watermass and continental weathering reconstructions from the Southeast Pacific

Creator:: Muratli, Jesse M.
Abstract:: Sediments of the central Chile margin record changes in ocean circulation and continental erosion associated with large–scale climate change. Here Antarctic– influenced Southern Ocean currents flow equatorward, forming a link between the high– and low–latitude oceans. Part of this link, Antarctic Intermediate Water, is an important conduit that ventilates South...

High-resolution sampling of particulate organic carbon in a coastal upwelling system

Creator:: Holser, Rachel R.
Abstract:: Summertime, wind-driven upwelling off the Oregon coast delivers nutrient rich water to the surface that fuels the autotrophic production of particulate organic carbon (POC). This POC can be transported horizontally by fluid motions and vertically by sinking to the bottom where it can be entrained in the benthic boundary layer...

Differentiating freshwater contributions and their variability to the surface and halocline layers of the Arctic and subarctic seas

Creator:: Alkire, Matthew Buckley
Abstract:: Dramatic and ongoing changes pervading the Arctic and subarctic seas over recent decades have motivated this effort to track and better understand hydrographic variability using chemical tracers. Particular emphasis has been paid to differentiating freshwater contributions to upper layers: namely Pacific water, meteoric water, and sea-ice melt/formation. Data collected in...

Bio-physical interactions of small pelagic fish schools and zooplankton prey in the California Current System over multiple scales

Creator:: Kaltenberg, Amanda May
Abstract:: Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving this instability...

Mantle melting and heterogeneity along mid-ocean ridges : insight from basalt geochemistry along axial depth and morphologic gradients for intermediate spreading rate systems

Creator:: Russo, Christopher J.
Abstract:: This investigation focuses on gaining a better understanding of the complex relationship between melt generation, source variability and mid-ocean ridge morphology. The approach adopted here uses a variety of geochemical techniques to evaluate the ability of 'global' models to predict regional scale geochemical variability associated with axial depth and axial...

Age, chemistry, and tectonic significance of Easter and Sala y Gomez Islands

Creator:: Clark, James Gregory, 1948-
Abstract:: Easter Island and Sala y Gomez are part of the Sala y Gomez Ridge, a broad band of high topography and scattered seamounts extending ESE from the East Pacific Rise. It has been proposed that the Sala y Gomez Ridge results from the movement of the Nazca Plate over a...

Deformation in the Peru Trench, 6⁰-10⁰S

Creator:: Prince, Roger Allan
Abstract:: Detailed surveys of several segments of the Peru Trench show that the region between 6° to 10⁰ S is an area of recent deformation. Seismic reflection records across the axis of the trench show faulting, uplift, and tilting of the sedimentary fill and the acoustic basement. Uplift of the acoustic...

Chile trench : extensional rupture of oceanic crust and the influence of tectonics on sediment distribution

Creator:: Schweller, W. J. (William John)
Abstract:: Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...
